Size: 32

Offset: 0x78

Access: RW

Access mode: SECURE | PRIVILEGEMODE

Note: The processor must make a secure, privileged bus access to this register. You can configure processor mode settings in the control registers of the ARM Cortex-A53 MPcore processor. For more information about processor modes, please refer to the ARM Infocenter.

Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.
